  • the present invention relates to a surgical instrument with a handle and an operating element arranged on the handle.
  • Surgical instruments with handles are known in the prior art in various embodiments.
  • the handles are often formed as hollow handles, with a drive shaft or the like, is guided by the hollow handle. It can be arranged on the handle directly controls for switching on or off the surgical instrument. Since the handle may come in contact with bodily fluids or other fluids during surgery, some protection of the controls must be provided. Particularly critical for the instruments, however, are those needed after surgery Cleaning, in particular for reprocessing by means of steam sterilization. It has been proposed to cover the controls by means of a foil. It has been found, however, that in particular the assembly of the film is relatively time consuming and therefore expensive. Another disadvantage of the known solution is that after a variety of uses, the film can tear. However, such damage to the film lead to unwanted leaks.
  • the surgical instrument according to the invention thus has the advantage that it has a secure seal against potentially penetrating liquids, wherein according to the invention a long life is ensured.
  • a circuit board assumes a fluid-tight separation of an inner region of the housing from an environment.
  • the circuit board has a dual function of a switching operation and a fluid-tight separation of an inner housing portion from an outer side. In this case, no separate separating element, such as a film or the like, necessary.
  • a switch is arranged in a passage opening of a handle, wherein the switch comprises an actuating element, the circuit board and a resilient contact element, in particular a spring washer made of conductive material or a spring element coated with electrically conductive material.
  • a seal is effected by means of the circuit board and a sealing element, which is arranged on an underside of the circuit board.
  • the sealing element seals against the Housing of the handle off.
  • the sealing element is circumferentially closed, so that on the circuit board in the inward direction starting from the sealing element sensitive components or contacts can be arranged, which are protected against the ingress of moisture.
  • a bottom of the circuit board is protected from moisture.
  • a groove is provided, in which the sealing element is arranged.
  • the sealing element can create excellent on the walls of the groove and seal there.
  • the switch comprises a guide plate for guiding the actuating element.
  • the actuating element preferably has a guide pin, which is guided in a recess formed in the guide disk.
  • the switch comprises a cover which is fixed to the handle, wherein the cover comprises at least one opening for receiving the actuating element.
  • the actuating element comprises at least two lugs, preferably three lugs, which engage behind an undercut formed in the cover. This avoids that the actuating element can fall out of the cover.
  • the guide disc rests on the circuit board.
  • a bias voltage can be exerted on the circuit board via the guide disk, wherein the circuit board in turn transmits the biasing force to the sealing element.
  • the spring washer comprises a plurality of contact feet on an outer periphery, which are in contact with a contact on the circuit board. As a result, for example, when pressing the actuating element, a central region of the spring washer can be pressed onto the circuit board and so an electrical contact can be made via the spring washer.
  • the circumferential sealing element is preferably formed as an O-ring. This allows a particularly cost-effective design can be achieved.
  • a surgical instrument according to the invention is described in detail with reference to the figure.
  • FIG. 1 is a schematic plan view of a surgical instrument with a hand-operated switch according to an embodiment of the invention, a schematic, exploded perspective view of the surgical instrument with a hand-operated switch, and

  • the handle 3 is a substantially cylindrical, hollow handle, through which a shaft or the like is guided.
  • the handle 3 comprises a housing 4, in which a passage opening 5 is provided.
  • the manually operated switch 2 is arranged in the passage opening 5.
  • the manually operated switch 2 comprises an actuating element 6 in the form of a push button, wherein the actuating element 6 comprises a central guide pin 6a and three radially outwardly projecting lugs 6b.
  • the hand-operated Switch 2 further comprises a circuit board 7 having a top 8 and a bottom 9, as a resilient contact element, an electrically conductive spring washer 1 1, a guide plate 13 and a sealing element 12.
  • the hand-operated switch of this embodiment comprises a total three individual switching devices, for example, a switching device for a forward, a switching device for a return and a switching device for an oscillating movement of the surgical instrument.
  • the three switching devices are arranged directly adjacent to each other, wherein in the housing 4 of the handle 3, a corresponding recess 17 is provided (see Fig .. 2).
  • the actuating element 6 is arranged in an opening 15 a of a cover 15.
  • the cover 15 in this case comprises an undercut 15b, behind which engage the lugs 6b of the actuating element 6.
  • the guide pin 6a of the actuating element 6 is arranged in a guide opening 13a of the guide disk 13.
  • the guide plate 13 is located directly on the upper side 8 of the circuit board 7.
  • the sealing element 12 in this embodiment is an O-ring, which is arranged on the underside 9 of the circuit board 7.
  • a first contact 71 and at the bottom 9, a second contact 72 is provided.
  • the circuit board 7 of the embodiment is annular.
  • two lines 10 are fixed in a known manner on the second contact 72.
  • the leads 10 are passed through the hollow handle to a motor control of the surgical instrument.
  • the sealing element 12 is arranged in a circumferential, U-shaped groove 14.
  • the circuit board 7 is arranged such that the circuit board 7 itself provides a fluid-tight separation from an inner region 4 a of the housing to a surrounding area 18.
  • the circuit board 4 also has a separating function between the inner area 4a and the surrounding area 18.
  • the circuit board 7 can be used as a separating element, so that no additional component, such as a film or the like, is necessary.
  • the plate-shaped cover 15 of this embodiment has three openings 15a for accommodating a total of three switching devices. As is apparent from Fig.
  • the cover 15 is screwed by means of two screws 16 in the housing 4 and fastened there.
  • a recess 17 is formed in the housing 4 to completely receive the cover 15 so that the cover 15 does not project on an outer side of the handle.
  • the cover 15 thus presses in the mounted state against the guide disk 13, which rests on the upper side 8 of the circuit board 7.
  • the circuit board 7 is also pressed radially inwardly against the sealing element 12. If a switch is to be actuated, an operator exerts, for example with a finger, a radially inwardly directed pressure on the actuating element 6. This is, as indicated in Fig.
  • the spring washer 1 1 four contact feet 1 1 a, which rest on the first contact 71 formed on the upper side 8 of the circuit board 7.
  • Another center contact 73 is formed at the top below the central region of the spring washer 1 1. If now the actuator 6 is pressed in the direction of arrow A, this comes with the spring washer 1 1 in contact and presses the center of the spring washer 1 1 against the central contact 73.
  • About a provided through the circuit board 7 via 18 is thus a connection between the contacts at the top and the bottom, where the leads 10 are fixed, made. This can drive the surgical instrument.
  • the invention also has the advantage that, where appropriate, the complete switch 2 can be dismantled again and, for example, in the case of a defect of a component, this can be easily replaced. Nevertheless, even after a reassembly of the switch can always be ensured that no moisture can penetrate into the inner region 4a of the housing 4.
  • the assembly of the switch 2 is significantly simplified, since only the components in the order sealing element 12, circuit board 7, spring washer 1 1, guide plate 13 and switching element 6 must be arranged one above the other and then only the cover 15 by means of screws 16 on the housing. 4 fixed.
  • the sealing element 12 can be easily inserted into the groove 14, so that a tightness is always guaranteed with each assembly.
